Tonga's transition to hybrid substrate notes — a polymer-paper composite rather than full polymer — reflects a practical compromise for small island economies where humidity and handling conditions degrade pure cotton-paper notes quickly but full polymer conversion carries higher unit costs. De La Rue's hybrid product attempts to split that difference, offering improved durability without the wholesale infrastructure changes that accompany a full polymer rollout.
The W prefix in the Pick reference denotes the World Banknote catalogue's hybrid and polymer series — a classification distinction, not a separate issuing event.
